MongoDB 4.2 has gone generally available, offering new features that can boost productivity and improve MongoDB life. The company is encouraging users to share their experiences with these features, including how they plan to use them or what difference it has made to their work. A contest, the 4.2 GA Challenge, is being held where participants can submit their ideas for applying MongoDB 4.2 features, with potential prizes of up to $1000 in Atlas credits. The challenge runs until the end of September and users can enter by filling out a form on the MongoDB website.
